关键词： Add-window interpolation;Harmonic and inter-harmonic;Small hydro

摘要： It is significant to boost the construction of small hydropower stations in mountainous areas due to the source water's abundance and big fall. However, the instability of small hydro increases the power quality problems such as harmonic and inter-harmonic when synchronizing and brings about lots of difficulties in the rapid development. To solve the power quality problems is an important bottleneck in the development of small hydro. This paper bases on the currently available harmonic and inter-harmonic detection methods, focuses on the specific situation of small hydro synchronization and puts forward an add-window interpolation FFT algorithm. Meanwhile, comparisons among several situations adopting different window functions are made and simulations in MATLAB are processed. The results show that the add-window interpolation FFT algorithm can overcome the picket fence effect, frequency spectrum leakage and aliasing. When choosing window function, employing Harming window is more appropriate for harmonic and inter-harmonic detection arose by the synchronization of small hydro. &copy;2013 Asian Network for Scientific Information.

摘要： In order to increase the accuracy ofpower quality disturbance detection in noising environment, this study puts forward a denoising algorithm ofpower quality distu?bance based on self-adapting to neutral fuzzy control. It establishes a structure with double-input and single-output neural network fuzzy system. Meanwhile, it presents the principle of denoising and makes a simulation analysis on disturbance circumstances with colored noise such as harmonic wave, voltage sag, voltage swell, voltage interruption etc. The results indicate that the proposed algorithm can well remove the signal-disturbing noise in grid. The waveform is visual clarity;the process ofanalyzing and calculating is simple and fast;the data got from calculation is few, which make the disturbance denoising ofpower quality more practical. &copy;2012 Asian Network for Scientific Informaction.

摘要： 岸电电源是在船舶制造、远洋钻井平台、码头等方面应用非常广泛的稳频稳压电源,但它对输出电压波形的稳态精度、动态性能等要求较高。通过对现有各种逆变控制方法进行研究和比较,在建立和分析岸电电源三相逆变器数学模型的基础上,针对它在旋转αβ坐标系下的特点,提出了一种神经网络内模控制和PID控制相结合的复合波形控制策略。建立了3层BP神经网络内部模型,并将其作为三相逆变器的内部模型,预测实际输出,采用PID控制器在线修正、补偿内部模型与三相逆变器之间的模型失配。对比仿真和实验数据,可以看出：当系统接阻性负载或整流性负载时,该控制方法所得的稳态电压误差和输出电压的谐波畸变率均小于其他控制方法,表明该策略控制下的岸电电源稳态精度高、输出波形质量好,具有一定的工程实用价值,能很好地应用于岸电电源逆变波形控制。

摘要： Neighbor embedding algorithm has been widely used in single-image super-resolution (SR) reconstruction, which makes the assumption that neighbor patches embedded are contained in a single manifold. However, this is not true for SR because of "one-to-many" mappings between low-resolution (LR) and high-resolution (HR) patches. To overcome the problem, we believe that textures may be contained in multiple manifolds. Under this assumption, by considering that the middle-frequency information of LR images has greater correlation with high resolution image than low frequency. We propose an improved single-image super-resolution algorithm. First, the low-resolution test and train image is decomposed into its middle-frequency and low-frequency components by applying the Gaussian low-pass filter. Then, we use locally linear embedding (LLE) to estimate HR patches for middle-frequency and low-frequency components of the low-resolution test image, respectively. Finally, two HR patches are fused into one by using fusion rules and all HR patches are merged to obtain the final HR image. The experimental results show that the proposed method performs better in both quantitative and qualitative evaluation compare with several NE-related SR approaches and the bi-cubic interpolation. &copy;2012 Praise Worthy Prize S.r.l.

关键词： Fourier series;SPWM;harmonic wave;analyze

摘要： A mathematical model for the output waveform of SPWM VSI (voltage source inverter) is created specific to the harmonic problem of SPWM voltage source inverter. Through theoretical analysis and calculation, we can get the distribution regularity of the output harmonic wave in the process of frequency conversion and voltage transformation. Utilizing the matlab to verify the simulation, we can get such results like "frequency conversion will lead to the shift of the harmonic wave's distribution center", "voltage transformation will cause the valuable change of the harmonic wave and the valuable change direction of harmonic wave is opposite to that of the fundamental wave". All of these will have significant guide meaning to the application of SPWM.

摘要： The distributed architecture of a multi-camera surveillance system is given, a data fusion scheme using path model and estimated target shape changes is described, and a collaborative algorithm in distributed multi-camera surveillance system is proposed in order to track people reliably. Based on the results of multi-camera data fusion, the proposed algorithm allocates cameras to objects according to task priorities, the distance between camera and target and the visibility of targets, which is characterized by the system assigning cameras to the visible target with high priority and the nearest distance to the camera. It is called Priority and Distance Algorithm (PDA). The Quality of Service (QoS) function is introduced to describe the system performance. Experiment results show that the proposed method can coordinate cameras to track people reliably and has good robustness. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.
